The retractable and tangle-free design of this boltBOX lets you neatly charge and sync your Apple devices. The boltBOX extends up to 3 feet and retracts inside its case. This is the perfect solution for on-the-go lifestyles. Magnetic Lightning connectors stay in place when the cable is retracted. This cable features a slim barrel design so you can charge and sync your device when using a case (or a backup battery case). It has been designed to even work with the larger and more protective cases. Works with iPod touch (5th generation), iPod nano (7th generation), iPhone 5s, iPhone 5c, iPhone 5, iPad Air, iPad (4th generation), iPad mini with retina, and iPad mini.
